Overview of Virtual LANs

A Virtual LAN is a group of location- and topology-independent devices that

communicate as if they were on the same physical local area network (LAN). Extreme

Networks switches have a VLAN feature thatenablesyou toconstruct broadcast domains

without being restricted by physical connections.

The VLAN Manager creates and manages VLAN for Extreme Networks devices only. It

does not handle other third-party devices, even though third-party devices can be

managed through the Inventory Manager.
